Meanwhile, Yuzu knows nothing of this and struggles to bake a cake for her first Christmas together with Mei. While her excitement builds, Mei comes home and breaks the news that she won't be able to join their Christmas Party due to student council work...
Mei-san isn't the diligent, 
perfect student you think she is.
Mei-san ist nicht die gewissenhafte
Musterschülerin, für die du sie hältst.
Mei-san no es la alumna perfecta
que crees que es.
Mei-san no es la alumna perfecta
que crees que es.
Cette fille, c’est pas l’élève modèle
que tu t’imagines.
Guarda che Mei-san
non è la studentessa perfetta che tu credi sia...
Mei-san não é a aluna perfeita
e comportada que você acha que é.
Мей — не порядочная пай-девочка,
какой ты её считаешь.
